A Reusable Polymeric Sensor Based on Green‐Synthesized CQDs@ZIF‐8 for the Rapid Detection of Nitro‐Explosive Picric Acid

Advanced Materials Interfaces, EarlyView.
This study presents the rational design and synthesis of a highly luminescent polymeric nanocomposite. Initially, highly fluorescent carbon quantum dots (CQDs) are synthesized via a facile hydrothermal method using citric acid and β‐alanine as precursors, followed by rigorous purification through centrifugation and filtration.
